Chocolate and mint are one of those combinations that you either love, hate, or just have to be in the mood for. I fall in the last category.
I don’t typically turn to mint chocolate when I have a sweet craving. But, once in a while, I do swoon a bit thinking about Andes Mint cupcakes, peppermint fudge cake, or thin mints.
I’ve seen Girl Scouts selling cookies everywhere lately. The cookies are so delicious – no one has to beg me to buy any. But I opted to buy some of the cookies I might not make myself (Caramel Delights, anyone?), thinking I would try to make some others at home.
Thin mints are probably top of everyone’s list of favorite Girl Scout cookies. So, why not start there? I was a Girl Scout, after all.
I adapted Dorie Greenspan’s basic chocolate cookie recipe found in her book, Dorie’s Cookies. Her recipe yielded about 80 cookies, so I reduced it pretty dramatically. Not that I couldn’t eat 80 thin mints, but I’m not sure I want to. I also added peppermint extract to give the dough a perfect minty crunch.
The result is a crispy cookie with the perfect balance of mint and chocolate.
After baking, I coated the cookies with melty mint chocolate. I added just a dash of mint to the chocolate coating to make sure it wasn’t over-powering.
For melting the chocolate, I used the double boiler method. Place a heatproof bowl over a pot of barely simmering water. The steam from the water will heat the bowl and melt the chocolate.
The chocolate begins to thicken as it cools and can make things difficult. I found that leaving the bowl of chocolate over the double boiler while dipping kept cookies will keep it at the optimal consistency. Just the chocolate a stir after every second cookie or so.
Let the chocolate set and the cookies will ready to devour!

What You’ll Need
Ingredients
- Flour: I use all purpose flour in this recipe
- Cocoa powder: Unsweetened Dutch-processed baking cocoa powder gives these cookies the perfect chocolaty flavor.
- Butter: Unsalted, as usual, and softened to room temperature.
- Sugar: White granulated sugar for sweetness.
- Egg white: To help bind the ingredients together. Save yolk for a creme brulee.
- Flavoring: Vanilla extract (homemade recipe here), peppermint extract (used in both the dough and the coating) and a pinch of kosher salt.
- Chocolate: Melting chocolate for the coating. Use a bar of dark or semisweet chocolate, coarsely chopped. I prefer dark chocolate in this recipe.
- Vegetable oil: Just a touch to make the melted chocolate smooth and dip-able.

How to Make Homemade Thin Mints
These homemade thin mints take a little bit of extra effort between the rolling and the cutting and the dipping, but they are so worth it. I promise. After chilling the dough, preheat your oven to 350 and line the baking sheets with parchment paper.
Be sure to check out the full recipe and ingredient list below
Make the cookies
- Using a stand mixer fitted with the paddle attachment or with a hand-held mixer, beat the butter and sugar together on medium speed until smooth and creamy, about 3 minutes.
- Beat in the egg white followed by the vanilla and peppermint extract. Gradually add the flour in 3 additions, beating just until incorporated after each one. Scrape down the sides of the bowl as needed.
- Divide the dough in half. Working with one half at a time. Place the dough between two pieces of parchment paper and roll it to a ¼ inch thickness. Leaving the dough in between the parchment paper, transfer it to a baking sheet. Refrigerate for at least 3 hours or freeze it for 1 hour.
- Working with one slab of dough at a time. Remove the top layer of parchment paper and cut circles with a 2-inch cookie cutter. Place the cookies on the prepared baking sheets about 1 and ½ inches apart. Gather the scraps of dough, reroll and chill to continue cutting and baking.
- Bake for 15 to 18 minutes, until the cookies feel firm to the touch. Cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Make the coating
- Combine the chocolate, oil, and extract in a double boiler or a medium heatproof bowl set over a pot of barely simmering water. Stir continuously until melted and smooth.
- Dip each cookie into the melted chocolate, turning with a fork to coat and tapping off any excess. Place cookies onto a parchment-lined baking sheet. Refrigerate the cookies until set, about 10 minutes. Cookies are best when served cold.
Handy tip:
Bake these cookies ahead of time and keep them in your freezer. Then when you have a craving for thin mints and can’t find a girl scout, all you’ll have to do is make the coating and dip the cookies. Voila!
Tips For Success
- When you first beat in the egg white, the dough may appear curdled, this is normal – don’t panic!
- When refrigerating or freezing the dough, it’s okay to stack the slabs of rolled dough on top of one another (with a layer of parchment in between).
Storage & Freezing
- The dough can be rolled out and kept in the refrigerator for up to 3 days or frozen for up to 2 months. Cut and bake as directed, even straight from the freezer.
- Baked (uncoated or coated) cookies will keep for up to 7 days in an airtight container stored in the refrigerator or up to 2 months in the freezer.

Can I use bittersweet Ghirardelli for the coating?
I don’t see why not.
Has anyone tried this recipe with a flavoring other than mint? Not a huge mint fan personally, but I love orange and chocolate together. I was thinking about trying it with orange extract.
I haven’t had any comments from readers saying they’ve used a different extract. But I will say, chocolate and orange are great together and that would be a delicious cookie.
Can you substitute ghee for the vegetable oil in the chocolate?
I don’t recommend it since I haven’t tested the recipe this way.
These were decent but they didn’t taste anything like thin mints. Not minty enough
Hi Danielle! I’m sorry you didn’t find the cookies to be minty enough. I find the mint extract to be quite strong and always hold back when using it. You can try adding more extract the next time you make them.
I am not sure if I mismeasured or what but these cookies weren’t that good for me. They tasted like unsweetened chocolate biscuits topped with chocolate.
what kind of dark cocoa powder? does it matter the percent and if its unsweetened/ sweetened?
Use unsweetened Dutch-processed cocoa powder.
is any unsweetened one ook
Are you referring to the cocoa powder? It must be Dutch-processed.
Can I substitute anything for oil in this recipe?
Thanks,
You can use coconut oil instead of vegetable oil. You only need 1/2 teaspoon to help the chocolate melt smoothly.
I am actually a Girl Scout Leader. These cookies were amazing and exactly like the Girl Scout version. I used them to help my girls get a badge.
The texture of the cookie is really similar to the real thing but you need to add WAY more peppermint to the base in order to match the thin mint flavor. There is barely any mint flavor following the original recipe.
Has anyone tried doing this as a slice and bake? Putting dough into a log and freezing first?
Thank you
Yes! It worked very well as a slice and bake. I found it much easier to get even shaped cookies.
